Just tested it, and it somewhat works you have to relog after it starts or the effects of Aporkalypse will still be there after you relog the clock will be frozen, and Aporkalypse won't happen again
Edit: I did more testing and during night its always full moon and thunderbirds still shoot 10 lightning bolts. Heralds still spawn iron hulks are always active so its basically the same but without the tint and pigs go outsides
